CLEVELAND, OHIO, A CORPORATION OF OHIO CUTTING OR SCORING MACHINE Application led. May 26, 1928. Serial No. 280,825.

r1`his invention relates'to a cutting or scoring machine, and has particular utility in connection with the manufacture of certain clay products, although not limited alone to such use. f

In order to describe a definite embodiment it is'especially adapted, the description herein will treat of the machine in connection with the (production of a hollow clay conduity or tile used as a kbasesupport for underground pipes. i f

. Underground pipes used in the transmissionV of steam, hot Water, or other liquid or gaseous materials, should be supported upon a suitable base, ordinarily in the form of aV hollow drain tile or conduit having an open.

' evenly.

' ing provided in its upper side intermediate its ends to accommodate the enlarged annular connecting portions of the pipes. T heseopen-l ings are formed in the tile by cutting a plug or section out of the upper lmiddle part there! of while the tile is green However, it was found that when the plug was cut entirely out of the green tile that the subsequent baking operation resulted in the remaining parts of the tile contracting and expanding untening the same in its original position by means of pins, so that its expansion and conktraction during baking and cooling would be uniform throughout the tile.

An object of the invention is to provide ,a cutting or scoring machine wherein a plu-y rality of cutting or scoring elements may be actuated by a common operating means so as f to function in a plurality of different pre-v i scribed planes.

A morespecific object is to provide a machine capable of cutting or scoring the walls of a tile or conduit in such manner that a contraction oreXpansion of they tile during baking will beY uniform. v

"Another objectv is'to provide a machine capable of uniformly and economically cutting plugs from a tile.

This brought about the practice of' l cutting the plug from the tile and then fasy Another object is to scoring machine forme of a relatively few number of parts, and of simple and economic construction.

Other objects and advantages will become apparent as kthe detailed description progresses.

An embodiment of the invention is illus-y trated in the accompanying drawings, where- 1n Fig. 1 is a side elevational view of the machine mounted on a belt conveyor frame;

Fig. 2 is an end elevational view of the machine also mounted on the belt conveyor frame; i

Fig. 3 is a side elevational view of the machine, a tile or conduit being shown by dash lines in position for cutting out the plu Y Fig. 4 is an end'elevational view o? the machine, certain parts being indicatedin sectioi and a tile being shown by dash lines; an

Figs. 5, 6 and 7 are end, top and side views, respectively, of the tile, with the plug entirely removed and portions of the tile shown Y in section. v

In the drawings and throughout the specilication like numerals will refer to like parts.

The machine is shown, and will be described, as mounted upon the frame of a belt conveyor, although the conveyor, as well as its driving motor, form no part of the pres- L ent invention, since the machine 'may be otherwise mounted and used.

The conveyorl frame comprises vertical supporting legs 1 having the spaced parallel longitudinally extending frame members 2 secured to their upper ends. The rearfend of the members 2 is provided with openings within which are arranged the take up boxes 3. These boxes adjustably house bearings for the shaft 4 which carries the pulley 5. A drive motor 6 is located adjacent the front vend of the conveyor, being operatively connected through a train of gears 7, 8, 9 and l() with the shaft 11 which carries the forward pulley of the conveyor mechanism.- A suitable clutch mechanism 12 operable by the lever 13 through the shaft 14 enables the conveyor belt to be stopped or started at e provide a cutting or c will, while a pivoted transversely extending plate 12a operatively connected with a'slot 13a arranged in a segment arm V 13b carried by the lever is positioned inorlremoved from the path of the articlesupon the conveyor belt upon actuation of the lever 13. The conveyor b elt 15 `of course, entends faround the rear andforward pulleys.

A filler member 16 is arranged between the Y u'iperl edges of lt'he members 2a'nd the belt l5, so that the tiles will 'be [firmly supported as they are carried by the belt through the cutting machine. Vertically extendingf arms 17 are connected'to the members 2 and carry longitudinally extending' guides 18, for'the nersides-to-conform to .theshape-of the tiles.

Of

^ course, this rotation of the shaft 41, in turn,

46 and 47 through the pinions 48 and 49,

the conveyor belt; rvment of theshafts provides the approximate thereby causing the cutting or scoring knives to be swung through an are. In a like manner, the bevel gear 43 drives the shafts 53 and 54 through the pinions 57, .whereupon the cutting or scoring vknives 59 are also swung through an are. It should be noted that the shafts 46, 47,v 53 and 54 are angularly arranged with respect to the main shaft 41k and the plane of the upper side' of This angular arrangetaperwhich the cutting knives are to impart to the cut edgesof the tile. Since the eutting knives' are longitudinally adjustable,

v'their lengths may be varied to change their arcs of travel, thereby diminishing orincreasing the vchord of such arcs and lhence the Ylength of the straight line cut.

distance between the spacing blocks 24, the

The

l vratio between the gear elements, and the an- Vgular arrangement of the shafts are all predetermined to the end that the knife adjustment will take care of any desired changes inthe character of the cut, to suit different sizes of tiles as may be passed through the machine.` It should also be observed that the ymachine is double acting, so to speak,

u lie ysinceafoiwvard movement of the operating handle will cause the cutting knives to rotate in one direction while a backward nio-venient'of the yhandle will cause them to rolows The tiles 61 are placed on the conveyo-r belt 15, either manually or automatically, as

desired, and are carriedforwardly thereby between the guides 18. As each tile comes into the 4proper cutting position the operator,

by means of the clutch operating lever 13,

stops the movement of the conveyor belt and I at'the same time the plate 12a is positioned l rthrough their predetermined are and are eflin' the path 'of the tile and maintains the same in the proper cutting position. The handle'44, which is at one extreme of the spacebetween the blocks 24', is then swung by 'the' operator to the other eXtreme position. This movement of the handle causes the knives 52 to swing through a prcdeter mined are and effect the longitudinal cutting of the tile'Gl along, the lines 62. At the same time the knives 59 are swinging fecting 'the transverse l'cutting of the tile along the lines 63. After the handle 44 has reached its limit` of travel, vthe operator operation is repeated in the same manner as the following tiles are consecutively brought into cutting position, it only being necessary, however, to move thehandle in one direction for each cutting operation depending upon its position.

As previously pointed out, the longitudinal adjustment of the cutting knives determines the character of the cut effected thereby. If it is desired to have a clean cut the knives may be adjusted to that end, or they -may be so arranged that the tile will be simply scored thereby. Preferably, the knives V'are so adjusted that the longitudinal and transversecuts will be clean for the greater part ot their lengths but will be simply scored adjacent their meeting extremities. The tile may thus be cut while green without completely removing the plug. After the baking and cooling of the tile the plug may be readily knocked out. Therefore, expansion and contraction of the tile is kept uniform during these operations.

The knives 52 may also be adjusted axially of the shafts 46 and 47 by means of shims between t-lie knives and the members However, these knives must always be located above the upper edge of the guides 18.
